Also, the phrase "this number value" refers 39 to the number value represented by this Number object, that is, the value 40 of the internal [[Value]] property of this Number object. 41 42 Author: christine (at) netscape.com 43 Date: 12 november 1997 44 */ 45 var SECTION = "15.7.4"; 46 var VERSION = "ECMA_1"; 47 startTest(); 48 var TITLE = "Properties of the Number Prototype Object"; 49 50 writeHeaderToLog( SECTION + " "+TITLE); 51 52 var testcases = getTestCases(); 53 test( testcases ); 54 55 function getTestCases() { 56 var array = new Array(); 57 var item = 0; 58 array[item++] = new TestCase( SECTION, 59 "Number.prototype.toString=Object.prototype.toString;Number.prototype.toString()", 60 "[object Number]", 61 eval("Number.prototype.toString=Object.prototype.toString;Number.prototype.toString()") ); 62 array[item++] = new TestCase( SECTION, "typeof Number.prototype", "object", typeof Number.prototype ); 63 array[item++] = new TestCase( SECTION, "Number.prototype.valueOf()", 0, Number.prototype.valueOf() ); 64 65 66 // The __proto__ property cannot be used in ECMA_1 tests. 67 // array[item++] = new TestCase( SECTION, "Number.prototype.__proto__", Object.prototype, Number.prototype.__proto__ ); 68 // array[item++] = new TestCase( SECTION, "Number.prototype.__proto__ == Object.prototype", true, Number.prototype.__proto__ == Object.prototype ); 69 70 71 return ( array ); 72 } 73 function test( ) { 74 for ( tc=0; tc < testcases.length; tc++ ) { 75 testcases[tc].passed = writeTestCaseResult( 76 testcases[tc].expect, 77 testcases[tc].actual, 78 testcases[tc].description +" = "+ testcases[tc].actual ); 79 80 testcases[tc].reason += ( testcases[tc].passed ) ?
